Davos Seaworth

While Mace Tyrell's host sat outside Storm's End waiting for starvation to do its work, a Flea Bottom smuggler ran a small black-sailed ship through the blockade with a hold full of onions and salt fish. The garrison ate. The castle held. The rebellion kept its southern anchor.

Stannis knighted him for it and then took the ends of four fingers for a lifetime of smuggling beforehand — a piece of justice so characteristic of the man that Davos reportedly considered it fair. Robert won a throne partly because one commoner was willing to sail into a siege for a lord he had never met.
